Measurements of conductivity (ac & dc) and dielectric constant (∈) have been made for amorphous alloyed samples of Se0.75Ge0.25−xAsxwith x= 0.05, 0.10, 0.15 and 0.20 at different temperature (289 to 389 K) and various frequencies (102to 105Hz). The conductivity and the dielectric constant of these glasses have been explained on the basis of the correlated barrier hopping (CBH) model. Recent...
